Money Hunt: The Mystery of the Missing Link was a 1984 contest video directed by David Hemmings and written by Gregory Ross.
The first person to solve the contest by calling a toll-free telephone number by the deadline would receive USD 100,000.
The video was hosted by John Hillerman, who narrated a short opening segment directly to the viewer explaining the contest rules and providing a few cursory hints.
The remainder of the video was a half-hour narrative, in the form of a farcical film noir detective story.
The detective, "Cash Hunt" (played by John Ashton) attempted to solve the same puzzle as the viewer.
